Am-Be sources in JAEA-FRSNishino, Sho 
; Tanimura, Yoshihiko ; Ebata, Yoshiaki*; Yoshizawa, Michio
We developed the graphite-moderated neutron calibration fields using Am-Be sources at the Facility of Radiation Standard in the Japan Atomic Energy Agency. The neutron spectra of the fields were evaluated by Monte-Carlo calculation and measurements using the Bonner Multi-sphere Spectrometer. Reference values of fluence rates and dose equivalent rates of H
(10) and H
(10) were determined from neutron spectra by measurements. Currently, our fields are available for calibration or performance test of neutron measuring instruments.
